Extruded Magnesium Anode Rod for Water Heater

Product Introduction:

Magnesium anodes are used in such systems, most commonly to protect
underground gas, oil and water pipelines.

In addition to pipelines, magnesium anodes are often used to
protect propane, water and chemical storage tanks, areas of ships
and port facilities that are not in direct contact with sea water,
power plants and irrigation systems.

Application:

The corrosion of metal in salt or fresh water or in soil can be
prevented by the use of galvanic anodes in a cathodic protection
system. Magnesium anodes are used in such systems, most commonly to
protect underground gas, oil and water pipelines.

Company Brief Introduction:

We are a professional anode supplier over 16 years ,mainly supply:

* Zinc anodes (ASTM B418-95 US MILL 18001K)
